    • A protective cover assembly (14) including a metal foil (20) with perforations (21), and a treatment on one or more surfaces of said metal foil. The treatment is a hydrophobic or oleophobic treatment, or both. The protective cover assembly (14) has an average specific acoustic resistance of less than about 11 Rayls MKS from 250-300 Hz, an average specific acoustic reactance magnitude of less than about 1 Rayls MKS from 250-300 Hz, and an instantaneous water entry pressure value of greater than about 11 cm. The perforations (21) of the metal foil (20) preferably have an average maximum pore size of less than about micrometers. The protective cover assembly (14) further includes an adhesive mounting system, and the preferred metal foil (20) is nickel.
